The Texans worked out former Baltimore Ravens fullback Ben Mason, wide receiver Juwan Green and cornerback Tae Hayes on Monday, according to a league source not authorized to speak publicly.
Mason is a former fifth-round draft pick from Michigan. The 6-foot-3, 254-pounder has played fullback and tight end and scored three touchdowns in a win over Nebraska after shifting from defensive tackle.
Cut by the Ravens this season, Mason signed with the New England Patriots practice squad and was released this month.
Green was previously with the Atlanta Falcons after going undrafted out of Albany. He was recently cut from the Falcons' practice squad.
A former undrafted free agent from Appalachian State, Hayes has played for the Jacksonville Jaguars, Miami Dolphins, Minnesota Vikings and Arizona Cardinals. He has 10 career tackles, one forced fumble and two passes defensed.
